Teil, basic data mapper for Postgres/Sqlite

Teil (pronounced /tail/)is a library that intends to make a connection to postgres (or sqlite) as simple as possible (with the limitations that this implies). Teil means part, portion or piece in german.

use teil::{Teil, fields::Serial};

#[derive(Teil, Debug)]
struct Account {
    #[teil(auto, primary_key)]
    id: Serial,
    #[teil(unique)]
    owner: String,
    #[teil(rename = "account_balance")]
    balance: f64
}

teil::config()
    .user("example")
    .password("password")
    .dbname("example_db")
    .host("127.0.0.1")
    .port(5432)
    .set().unwrap();

teil::create!(Account);

(Account {id: Serial::new(), owner: "Carlos".into(), balance: 420.00}).save().await.unwrap();
let account = Account::retrieve(1).await.unwrap();
println!("{:?}", account);

teil::destroy!(Account);

Features available for this crate
